From Almighty Scholar to Chief Scientist

The polishing liquid not only dissipates heat to the grinding disc, but also uses the small particles of internal polishing powder and the protrusions on the surface of the material to polish. After all, the final chip is engraved on the process of nanometers.

After a short thought, Lin Xiao finally made a choice: "Grab with both hands, and be firm with both hands."

In particular, the polishing process is not only used for polishing silicon wafers, the optical lens of the lithography machine in the future also needs to innovate the polishing process.

Under the bragging of the media in the past, carbon-based chips seem to have become a new field in which Huaguo can achieve cornering overtaking in the chip field, but obviously, the threshold of polishing technology alone is enough to keep Huaguo from thinking about engaging in carbon chips base chip.

Therefore, the polishing process is also an area where foreign countries sanction Huaguo.

A breakthrough in this field is imperative.

He opened the system panel and looked at his remaining truth points.

【283.5】

A fairly high number.

In the process of solving various problems of the lithography machine, there will definitely be some problems. If Lin Xiao really can't solve them, he will consider using truth points.

With so many truth points, of course we have to use them.

Of course, he also wants to know how many truth points are needed to solve his problem, so that he can make a mental preparation.

"The system can increase the polishing rate of silicon wafers by five times, and the combination of polishing abrasives and polishing liquid with a surface accuracy of about 1nm is stable. At the same time, the cost should not exceed twice the current cost. How many truth points are needed?"

"Based on the host's civilization level and the host's comprehensive ability, 10 truth points are needed."

Lin Xiao was taken aback for a moment: "What? Only 10 truth points?"

It's so cheap?

He now has nearly 300 truth points, and these 10 truth points are nothing at all!

"System, you actually look down on the polishing process so much?"

System: "This requirement does not require a breakthrough in finding the truth, it is just a matter of permutation and combination of various relevant knowledge of the host's civilization, so only 10 truth points are required."

Lin Xiao: "...Okay."

"Then you might as well send me off."

system;"……"

No reply yet.

Lin Xiao thought for a while, and then asked: "What about the optical lens polishing disc material and polishing liquid with an accuracy of 50-100pm-rms?"

System: "Need 11 truth points."

Lin Xiao's eyes gradually lit up.

Only 11 truth points? !

The requirements for the optical lens grinding disc of the lithography machine are obviously greater than the requirements for the grinding disc of the silicon wafer, and the result is only 11 truth points.

"System, this is the first time I found you so cute!"

Although the system does not care about the existing technologies of these earth humans, and has a completely "contemptuous" attitude, it is great news for him.

Because this means that he will be able to use a lower price to help Huaguo break through the sanctions imposed by almost all countries in the world!

Thinking of this, he couldn't help laughing out loud.

He wants Huaguo to produce their own cutting-edge chips for at least the next few years!

"Anyway, it's a breakout. From which direction is it not a breakout, let's start with the polishing process and complete the first breakout."

Afterwards, he spent 10 truth points and directly exchanged them for silicon wafer grinding disc materials and polishing liquid materials.

In the next moment, countless knowledge emerged in his mind.

Chapter 222 Ceramic Disc Materials

Spending truth points for the second time, Lin Xiao immediately felt the same feeling as the last time he exchanged the titanium-aluminum alloy, as if he had understood all the truths in the world for a moment.

However, it was probably because the materials obtained this time were not particularly important, so it didn't take long for him to have two more production methods and related processes in his mind.

"The material of this grinding disc...is it silicon carbide ceramic? Is it doped with a little tantalum element? The content is 0.1%... Well, it's amazing."

The material of this millstone caught Lin Xiao's eyes.

Indeed, as the system said, this material can be researched by arranging and combining existing knowledge, so he can easily see why this material is so good.

The expansion coefficient of tantalum itself is very small, and it only expands by [-] parts per million per degree Celsius. When it is doped into silicon carbide ceramics, the thermal expansion coefficient of the ceramic itself is very small, and the two become more excellent. up.

Of course, the most important thing is how to combine the two. If you can’t combine them, it’s useless, and the preparation process is given in the information provided by the system, and the preparation process can be called an idiot-level tutorial. As long as you can understand the words, you can create them.

To Lin Xiao's surprise, his requirement was that the cost should not exceed twice that of the original grinding disc, but now if it is prepared according to this process, the cost may be even lower.

This is perfect, and the cost is definitely lower than the production costs of companies in the United States, Japan and Germany.

At that time, when this kind of grinding disc can be mass-produced, Huaguo will be able to show the world the prestige of a "developed country grinder".

As for the polishing liquid, it is a colloid made of silicon powder and sodium hydroxide, which is also mixed with some other things. The cost is the same as before, but it is obviously cheaper than the polishing liquid they used before. a little better.

The production technology required for polishing liquid is even simpler.

All in all, once these two materials are put into production, it will probably take less than a few months. The most important thing is the time required to establish the production line in the process. After all, the relevant molds still need to be customized, and it takes a little time to prepare.

Of course, at least it has been able to predict when it will be successful, which is obviously better than that kind of stuffy research that doesn't know when it will be successful.

Lin Xiao breathed a sigh of relief.

After these two materials are produced, he doesn't have to worry about the production of silicon wafers.

With the production process of these two materials, he certainly doesn't need to worry about it himself. He can completely entrust this task to other people.

As for how to explain how he came up with this thing?

There is no need to explain at all, he finds good people and asks people to make things according to the process he specified, and it is impossible for others to question how he made them.

So Lin Xiao doesn't need to worry about it any more. He just needs to wait for a few months later when it comes that "my country's ultra-precision polishing process has made a breakthrough, which is comparable to the United States, Japan and Germany", "my country's silicon wafer production process has made another breakthrough, The production rate has been greatly improved" and other news.

As for other materials, don't worry about it for the time being, let's talk about it after the servo motor is produced.

As for the servo motor, he didn't intend to solve it with the truth point, but decided to do it himself. Although the servo motor also needs innovation in materials, Lin Xiao thought for so long and found a new way.

That is to say, starting from the structure, in addition to starting from the intelligence.

Starting from these two aspects, what is considered is not the field of material breakthrough that requires luck, but the consideration of knowledge in mathematics, physics, and information.

In this regard, Lin Xiao is very confident. Can Mathematics 5 and Physics 4 be covered?

"Take a good rest first, and start working when we return to Beijing tomorrow."

With this in mind, Lin Xiao lay down on the bed and began to rest.

……

Time passed quickly, a few days later.

Institute of Aeronautical Materials.

"Lin Xiao, yo, you still know how to come back."

Looking at the person in front of him, Lin Xiao greeted with a smile: "Academician Chen!"

Chen Bao was Academician Chen who brought Lin Xiao to the Institute of Aeronautical Materials.

It was here that Lin Xiao created a new material that could be used as an engine turbine blade.

"Why did you come here today? With such a group of people?"

Chen Bao said with a smile, and at the same time glanced at the people behind Lin Xiao.

Lin Xiao smiled and said, "Come here and borrow your material laboratory. I plan to research a new material, so I'm here."

"That's it, okay, then I won't delay you."

Chen Bao nodded, although he wondered what new material Lin Xiao was going to study, but after all, this should be someone else's project, so he didn't want to ask more.

Lin Xiao didn't explain too much to Chen Bao. He came here mainly to make his grinding disc material. However, after Dingguang Technology Company was established, it didn't have its own research institute, so he thought that he used to research aviation materials. So I have done research here, so I rented the laboratory here.

In fact, he can apply for funding from the country to build a research institute, but the research institute he wants to build will cost billions at least, and it will cost a lot to hire people in the future.

It's just that he hasn't done anything yet. It would be a bit embarrassing if he wanted the country to build such an expensive research institute for him, so he hasn't made this request to the country yet.

Of course, this is only temporary. After the silicon wafer material is produced, and then the servo motor is assembled, he can confidently ask the country to build a large research institute for him, and the country will definitely trust him even more. The ability in applied science, from materials to chemistry, to physics, etc., will be integrated first, and then expanded when it needs to be expanded.

No more to say, after he entered the research institute, he found the laboratory he had booked before. Because of the relationship, he can still borrow the laboratory of the Institute of Aeronautical Materials, and there are all kinds of equipment he needs in it. There are also requirements for polishing in instruments and aerospace materials.

Then, he turned his head and glanced at the people behind him, and said: "Okay, everyone, after getting familiar with the instruments here, our project will officially start. You all have basic skills in the field of ceramics, so I will do the rest. No more questions, what we want to develop is a new type of silicon carbide ceramic material."

"Okay, Professor Lin!"

The people behind him all responded.

These people are all post-doctoral fellows that Lin Xiao found in the School of Materials Science and Technology of Shangjing University. They are all of excellent professional quality. He hired them to work on the project in the name of a state-owned enterprise of Dingguang Technology Company.

There is no professor level hired, anyway, he already knows how to prepare, of course, no need to use a professor.

As for the postdoctoral fellows who learned that it was Lin Xiao, they naturally accepted it happily. Although Lin Xiao used to study mathematics and physics, the achievement of the bonding mechanism made him quite famous in the field of materials. of.

Of course, before the experiment officially started, they also had some issues to discuss. They just signed a non-disclosure agreement, but they didn't know much about the details of the experiment. They only knew that it was a ceramic material.

So someone asked: "Professor Lin, what is the use of our materials?"

Lin Xiao said with a smile: "Ultra-precision polishing, do you know?"

Several people were stunned for a moment, "Ultra-precision polishing? You mean, we are studying that kind of grinding disc?"

"Ah."

Lin Xiao nodded and said, "It's the material of this millstone."

These postdoctoral fellows suddenly felt a toothache.

Good guy, they just ran over to study this top-level material?

Didn't they fall into the pit?

I learned before that Lin Xiao hired them to do the project, so they agreed directly at the time. Looking at it now, it is self-inflicted.

There is no such breakthrough material in the whole of China, how many of their postdoctoral fellows want to complete the breakthrough?

Just kidding!

How much time does this take them.

It's just that they've all come here, they're all here, and obviously they're too embarrassed to propose withdrawal, so they can only wait for a while, and if there is really no hope of success, then let's talk.

Seeing them like this, Lin Xiao couldn't help but smile, he knew what they were thinking.

However, he didn't say much. After the experiment started, I believe these few people would be grateful for how lucky they were to be able to participate.

Then, he said: "Okay, there is no need to talk nonsense, I will show you our materials first."

He took out his laptop from the bag, and then opened the various materials he had sorted out for the new ceramic material doped with tantalum silicon carbide.

"You should know that in the polishing process, the thermal expansion coefficient of the grinding disc material is very low, so ceramics have become a preferred material, which itself has a relatively low thermal expansion coefficient, but how to make them lower? The element tantalum It's a choice."

"Look at the picture."

Introducing a new material, of course, requires pictures.

Lin Xiao has constructed the unit cell of this new material. In addition, he also calculated various properties of this material by means of calculating materials. Although the calculation results and detailed properties given by the system are still Some properties, but generally not too bad.

The calculation results have shown the advantages of this new material in terms of hardness, thermal expansion coefficient, and processing.

The processing performance of the material is also a key advantage, which has great significance for mass production.

And this new ceramic material has good processing performance, so it is easier to achieve mass production. Similarly, the cost will also be greatly reduced.

In this way, under Lin Xiao's introduction, these postdoctoral fellows thought they were free to come here, but now they look at it, hey~ it seems that they can really succeed?

Just talking about the calculated thermal expansion coefficient is really impressive, and it is absolutely suitable for use on grinding discs.

"That's it. However, our problem now is how to integrate the tantalum element with our silicon carbide ceramics and form such a unit cell, so this requires us to design the production process."

"Now I have an idea. Is it better to dope the tantalum element in a centrifugal way after melting the silicon carbide? This requires the speed of the centrifugation and the timing of our doping with the tantalum element."

"Of course, this matter is left to you."

After Lin Xiao finished speaking, the eyes of these postdoctoral fellows gradually lit up.

So, does it seem like there's a real chance of success?
